Just jumping on this thread, also would be great to star routes from the route page itself (the view where the route "plays") as well as the personal homepage where there's only hearts not stars to tag routes with. I generally use "My Routes" as my homepage but when I find an old route and open it up to look then want to "star" it, I can't do that very easily.
Thanks for the feedback Ewoud.
I very often create a route in plotaroute which I need to use on a Garmin device. I can sync my routes to Garmin by adding a star to this route in the 'my route' section but this is always a 2step approach, first save the route -> go to 'my route' > add star.
It would be more efficient if we had the option to add the star immediately when saving the route
